Earlier versions of Authenticator are unfortunately unable to export user data, so you will need to follow these instructions to make sure you do not lose access to your Google account during the Authenticator upgrade process.

Note: as of Authenticator 0.62, only devices running Android version 2.1 and later are supported.

First switch to text or voice verification codes. (You will switch back to using Authenticator verification codes in the following step.) Be sure to follow this process for all accounts you have configured in Authenticator.

Follow these instructions to download the new version of Google Authenticator from Google play and configure your Google Account in it.

Once you have confirmed as part of the previous step that you are able to successfully generate valid verification codes using the new Authenticator, it is safe to uninstall the old version of the app. Because both versions have the same icon, make sure to check the version number before uninstalling: you want to keep version 2.15.
